Benjamin Petersond2e0c792009-05-01 20:40:59 +0000334- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
335 received a new method, detach(). detach() disconnects the underlying stream
336 from the buffer or text IO and returns it.
337
Mark Dickinson33841c32009-05-01 15:37:04 +0000338- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
339 floats with absolute value over 1e50. Also remove length
340 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
341 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +0000343- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000344 format(complex(1, 2./3), '.5') now produces a sensible result.
345
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000346- Issue #5864: Fix empty format code formatting for floats so that it
347 never gives more than the requested number of significant digits.
348
Eric Smith6dc46f52009-04-27 20:39:49 +0000349- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

355 titlecase, but not their own uppercase.
356
Benjamin Peterson193152c2009-04-25 01:08:45 +0000357- Issue #5283: Setting __class__ in __del__ caused a segfault.
358
Mark Dickinsonad476da2009-04-23 19:14:16 +0000359- Issue #5816: complex(repr(z)) now recovers z exactly, even when
360 z involves nans, infs or negative zeros.
361
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000362- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000363
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000364- Issue #1869 (and many duplicates): make round(x, n) correctly
365 rounded for a float x, by using the decimal <-> binary conversions
366 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
367 consistently agrees with format(x, '.2f').
368
Benjamin Petersonae937c02009-04-18 20:54:08 +0000369- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
370 some builtin types.
371
Eric Smith0923d1d2009-04-16 20:16:10 +0000372- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
373
Eric Smith35e84722009-04-16 20:21:28 +0000374- Issue #5515: str.format() type 'n' combined with commas and leading
375 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000376
377- Implement PEP 378, Format Specifier for Thousands Separator, for
378 floats.
379
Mark Dickinson3370cce2009-04-17 22:40:53 +0000380- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000381 1e11, not 1e12. This avoids printing 13 significant digits in
382 situations where only 12 of them are correct. Example problem
383 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
384 long time.)
385
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000386- Issue #1580: On most platforms, use a 'short' float repr: for a
387 finite float x, repr(x) now outputs a string based on the shortest
388 sequence of decimal digits that rounds to x. Previous behaviour was
389 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000390 Another minor difference is that the new repr switches to
391 exponential notation at 1e16 instead of the previous 1e17; this
392 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000393
394 There's a new sys attribute sys.float_repr_style, which takes
395 the value 'short' to indicate that we're using short float repr,
396 and 'legacy' if the short float repr isn't available for one
397 reason or another.
398
399 The float repr change involves incorporating David Gay's 'perfect
400 rounding' code into the Python core (it's in Python/dtoa.c). As a
401 secondary consequence, all string-to-float and float-to-string
402 conversions (including all float formatting operations) will be
403 correctly rounded on these platforms.
404
405 See issue 1580 discussions for details of platforms for which
406 this change does not apply.
407
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000408- Issue #5759: float() didn't call __float__ on str subclasses.
409
Georg Brandlabc38772009-04-12 15:51:51 +0000410- The string.maketrans() function is deprecated; there is a new static method
411 maketrans() on the bytes and bytearray classes. This removes confusion about
412 the types string.maketrans() is supposed to work with, and mirrors the
413 methods available on the str class.
414
R. David Murraydc6da8a2009-04-09 22:16:43 +0000415- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
416 its clarity and its speed.
417
Matthias Klose091c7b12009-04-07 13:24:27 +0000418- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
419 to avoid compiler warnings.
420
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000421- Issue #3739: The unicode-internal encoder now reports the number of characters
422 consumed like any other encoder (instead of the number of bytes).

578
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000579- Issue #4688: Add a heuristic so that tuples and dicts containing only
580 untrackable objects are not tracked by the garbage collector. This can
581 reduce the size of collections and therefore the garbage collection overhead
582 on long-running programs, depending on their particular use of datatypes.

641 socket.SO_REUSEADDR on all connections so that the user no longer needs
642 to wait 120 seconds for the socket to expire.
643

Lars Gustäbel42e00912009-03-22 20:34:29 +0000652- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
653 forever on incomplete input. That caused tarfile.open() to hang when used
654 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
655 partial bzip2 compressed data.
656
Mark Dickinson79f52032009-03-17 23:12:51 +0000657- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonae681df2009-03-21 10:26:31 +0000674- Issue #5463: In struct module, remove deprecated overflow wrapping
675 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +0000676 struct.error instead of returning b'\xff\xff\xff\xff'. The
677 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
678 have been removed from the struct module.

700 source has already been decoded into str.
701
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000702- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
703 rotating the object pointer by 4 bits to the right.
704
Mark Dickinson87ec0852009-02-09 17:15:59 +0000705- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
706 it now forces its argument to double before testing for infinity.

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000718- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000719 were suppressing all exceptions. These include list() and bytearray().
720
Mark Dickinson1124e712009-01-28 21:25:58 +0000721- Issue #4707: round(x, n) now returns an integer if x is an integer.
722 Previously it returned a float.
723
Antoine Pitroub52ec782009-01-25 16:34:23 +0000724- Issue #4753: By enabling a configure option named '--with-computed-gotos'
725 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
726 evaluation loop is compiled with a new dispatch mechanism which gives
727 speedups of up to 20%, depending on the system, on various benchmarks.

Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000736- Issue #4838: When a module is deallocated, free the memory backing the
737 optional module state data.
738
Mark Dickinson8055afd2009-01-17 10:04:45 +0000739- Issue #4910: Rename nb_long slot to nb_reserved, and change its
740 type to (void *).
741
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000742- Issue #4935: The overflow checking code in the expandtabs() method common
743 to str, bytes and bytearray could be optimized away by the compiler, letting
744 the interpreter segfault instead of raising an error.
745
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000746- Issue #3720: Fix a crash when an iterator modifies its class and removes its
747 __next__ method.
748
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000749- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
750 function no longer attempt to call the __long__ slot to convert an object
751 to an integer. Only the __int__ and __trunc__ slots are examined.
752

756
Antoine Pitrouab868312009-01-10 15:40:25 +0000757- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
758 common cases are optimized thanks to a dedicated fast path and a moderate
759 amount of loop unrolling.
760
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000761- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
762 collecting the oldest generation) so that allocating lots of objects without
763 destroying them does not show quadratic performance. Based on a proposal by
764 Martin von Löwis at
765 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
766
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000767- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000768 having been closed (for instance, a read() call could return some
769 previously buffered data). Patch by Dmitry Vasiliev.
770
Antoine Pitrou05608432009-01-09 18:53:14 +0000771- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
772 flag to work properly. Furthermore, when specifying -u, the text stdout
773 and stderr streams have line-by-line buffering enabled (the default being
774 to buffer arbitrary chunks of data).
775
Raymond Hettinger35631532009-01-09 03:58:09 +0000776- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
777 instead of ints (reducing its size from 4 to 8 times thereby reducing
778 Python's overall memory).
779
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000780- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
781 an existing .py counterpart, override the co_filename attributes of all
782 code objects if the original filename is obsolete (which can happen if the
783 file has been renamed, moved, or if it is accessed through different paths).
784 Patch by Ziga Seilnacht and Jean-Paul Calderone.
785
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000786- Issue #4580: Fix slicing of memoryviews when the item size is greater than
787 one byte. Also fixes the meaning of len() so that it returns the number of
788 items, rather than the size in bytes.
789
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000790- Issue #4075: Use OutputDebugStringW in Py_FatalError.
791
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000792- Issue #4747: When the terminal does not use utf-8, executing a script with
793 non-ascii characters in its name could fail with a "SyntaxError: None" error.
794
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000795- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +0000796 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000797
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000798- Issue #3680: Reference cycles created through a dict, set or deque iterator
799 did not get collected.
800
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000801- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
802 where the tp_hash and tp_dict slots are both NULL.
803
Georg Brandlccc47b62008-12-28 11:44:14 +0000804- Issue #4759: None is now allowed as the first argument of
805 bytearray.translate(). It was always allowed for bytes.translate().
806
Skip Montanaro80072cb2008-12-23 03:51:14 +0000807- Added test case to ensure attempts to read from a file opened for writing
808 fail.
809

814
Antoine Pitrou621601a2008-12-17 23:18:19 +0000815- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
816 print elapsed times, not only when some objects are uncollectable /
817 unreachable. Original patch by Neil Schemenauer.
818
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000819- Issue #3439: Add a bit_length method to int.
820
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000821- Issue #2173: When getting device encoding, check that return value of
822 nl_langinfo is not the empty string. This was causing silent build
823 failures on OS X.
824
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000825- Issue #4597: Fixed several opcodes that weren't always propagating
826 exceptions.
827
828- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000829 context manager returns a value that cannot be converted to a bool.
830
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000831- Issue #4445: Replace "sizeof(PyBytesObject)" with
832 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
833 bytes instances. On a typical machine this saves 3 bytes of memory
834 (on average) per allocation of a bytes instance.
835
Christian Heimesa872de52008-12-05 08:26:55 +0000836- Issue #4533: File read operation was dreadfully slow due to a slowly
837 growing read buffer. Fixed by using the same growth rate algorithm as
838 Python 2.x.
839
Antoine Pitrou5504e892008-12-06 21:27:53 +0000840- Issue #4509: Various issues surrounding resize of bytearray objects to
841 which there are buffer exports (e.g. memoryview instances).
842
Georg Brandlf9734072008-12-07 15:30:06 +0000843- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
844 method on file objects with closefd=False. The file descriptor is still
845 kept open but the file object behaves like a closed file. The ``FileIO``
846 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000847
Antoine Pitroubc420402008-12-07 20:14:49 +0000848- Issue #4569: Interpreter crash when mutating a memoryview with an item size
849 larger than 1.

854
Walter Dörwaldc1651a02009-05-03 22:55:55 +0000855- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
856 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
857 step. This avoids problems with counting UTF-8 bytes that ignores the effect
858 of using the replace error handler in PyUnicode_DecodeUTF8().
